Cómo usar UseeFectect

import React, { useState, useEffect } from 'react';
function Example() {
  const [count, setCount] = useState(0);

  // Similar to componentDidMount and componentDidUpdate:  
  useEffect(() => {    
  	// Update the document title using the browser API    
  	document.title = `You clicked ${count} times`;  
  });
  
  return (
    <div>
      <p>You clicked {count} times</p>
      <button onClick={() => setCount(count + 1)}>
        Click me
      </button>

import React, { useEffect, useState } from "react";
import ReactDOM from "react-dom";

function Reddit() {
  // Initialize state to hold the posts

      // Pull out the data as usual
      const json = await res.json();

      // Save the posts into state
      // (look at the Network tab to see why the path is like this)
      setPosts(json.data.children.map(c => c.data));
    }

    fetchData();
  }); // <-- we didn't pass a value. what do you think will happen?

  // Render as usual
